A police officer said an explosion killed four people and wounded 10 in Iskandariyah, 30 miles south of the capital.

In Mishada, 20 miles north of Baghdad, a car bomb killed five civilians and wounded 14, another police officer said.

Three medical officials confirmed the casualty figures.

The attacks came a day after explosions killed at least 24 people in different parts of Iraq. Such bombings have increased since last year, along with Sunni anger over perceived mistreatment and random arrests of Sunnis by the authorities.

On Thursday, clashes outside of Fallujah between militants and Iraqi security forces killed at least five people and wounded 13, a local hospital there said.
